Today is Divine Mercy Sunday, a devotion introduced into the Church through the revelations made to St Faustina Kowalska (*1905 +1938). This is a summary of St Faustina’s life (the first canonised saint of the third millennium) which comes in the form of a foreword to her Diary / Autobiography.
The DIARY of Sister Faustina, written in the form of a journal, records the last four years of her life. It reveals the depths of her spiritual life and illustrates the high degree of her soul’s union with God. The Lord endowed Sister Faustina with tremendous graces: the gift of contemplation, a deep knowledge of the mystery of the mercy of God, visions, revelations, the hidden stigmata, the gifts of prophecy and of reading human souls, and also the rare gift of mystical espousal (Diary Introduction, p. 10, Polish Edition).
Here are some excepts of the Diary taken from http://www.faustina-message.com/index.htm. Click on the link to see more excerpts.
“God never violates our free will. It is up to us whether we want to receive God’s grace or not. It is up to us whether we will co-operate with it or waste it” (Diary, 1107).
“…I saw two roads. One was broad, covered with sand and flowers, full of joy, music and all sorts of pleasures. People were walking along it, dancing and enjoying themselves. They reached the end without realizing it. And at the end of the road there was a horrible precipice; that is, the abyss of hell. The souls fell blindly into it; as they walked, so they fell. And their number was so great that it was impossible to count them. And I saw the other road, or rather, a path, for it was narrow and strewn with thorns and rocks; and the people who walked along it had tears in their eyes, and all kinds of suffering befell them. Some fell down upon the rocks, but stood up immediately and went on. At the end of the road there was a magnificent garden filled with all sorts of happiness and all these souls entered there. At the very first instant they forgot all their sufferings” (Diary, 153).
“…How fleeting all earthly things are. Everything that appears great disappears like smoke and does not give the soul freedom, but weariness. Happy the soul that understands these things and with only one foot touches the earth” (Diary, 1141).
“…If a soul loves God sincerely and is intimately united with Him, then, even though such a soul may be living in the midst of difficult external circumstances, nothing can disturb its interior life. In the midst of corruption, it can remain pure and unsullied because the great love of God gives it strength for battle, and God also protects it in a special way” (Diary, 1094).
